Furthermore, by the integral formation of the sole and supports, the latter are held in place upon the sole and ing or becoming dislodged.

What is claimed is:

l. The method of forming a shoe insole, which consists in first slitting the sole blank inwardly a predetermined distance from the inner edge of the shank portion of the blank, then shaping a separate piece of material to conform in outline with the outer edge of the shank portion of the blank and having a wing on its opposite edge, then slitting said piece of material edgewise and longitudinally for a distance including said wing to form upper and lower layers, then r emoving part of the lower layer leaving the wing shaped portion in place, then beveling the inner out edge of said wing portion and securing the same in place within the slit formed in the shank portion of said blank, and then cementing the upper layer of said material to the lower layer and to the upper surface of said sole blank.

2. The method oi forming an insole for shoes which consists" in first slitting the sole blank inwardly along the inner edge of the shank portion to form a longitudinally extending pocket, then shaping a separate piece of material to conform in outline with the outer edge of the shank portion of the blank and form the same with a wing extension at its opposite edge, then slitting said piece of'material edgewise for a distance including said wing-extension to thereby produce upper and lower layers, then marking off the proper width and length of said wing extension upon the lower layer and removing the remaining portion thereof, then beveling the inner marked off edge of said wing extension and positioning said edge within the pocket formed in the shank portion of the blank, and then cementing the upper layer of said material to the upper surface of said blank and wing extension.

3. The method of forming an arch support on an insole for shoes which consists in first slitting the sole blank inwardly a predetermined distance at the inner edge of the shank portion to provide a longitudinal pocket therein, then shaping a separate piece of material to conform substantially with the outline of the outer edge prevented from shiftof the shank portion of the blank and having a wing on the opposite edge thereof, then slitting said piece of material edgewise for a distance including said wing to provide upper and lower layers of said material, then marking off with a templet the inner portion of said wing upon said lower layer and removing the remaining portion of the latter, then beveling the inner edge of said wing portion to the shape of a wedge and positioning said edge within the pocket formed in the shank portion of said blank and securing the same therein, and then cementing the upper layer of the material to thereto.

4. The method of forming an insole for shoes which consists in first slitting the sole blank inwardly a predetermined distance from the inner edge of the shank portion of the blank to provide a longitudinal pocket therein, then shaping a separate piece of material having a wing portion and an extension extending over a portion of the heel blank, then slitting said piece of material edgewise from the forward end thereof for a distance including said wing to provide upper and lower layers of said material, then marking off said wing from the lower of said layers and removing the remaining of said material forming said lower layer, then beveling the inner edges of said wing and extension and placing the beveled edge of said wing into the pocket formed in the shank portion of said slitted blank and in then cementing the upper layer of said material to the upper surface of said sole blank and to said wing portion.

having a longitudinally extending pocket formed in the inner edge of the shank portion of said blank, a separate piece of material having a portion secured within said pocket forming-a laterally extending wing upon said sole, and a portion integral with said material overlying the shank portion of the sole blank and cemented in place thereon.

6. An insole for shoes comprising a sole blank having a longitudinally extending pocket formed in the inner edge of its shank portion, a separate piece of material havinga portion secured within said pocket forming a laterally extending wing upon said sole, a portion integral with said material overlying the shank portion of the sole blank and a wedge shaped extension overlying a portion of the heel .of the sole blank, said overlys. portions being cemented in place upon said sole.
